Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






2. The second cervical vertebra; it forms the atlantoaxial joint with the first cervical vertebra - the atlas.






3. Skull bones that are part of the external bones of the cranium; located on the dorsal midline just rostral to the occipital bone.






4. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






5. Blood cell production; usually occurs in red bone marrow.






6. The bones of the pelvic limbs located between the tarsus and the phalanges.






7. The lay term for the most proximal joint of the equine digit - which is the joint between the large metacarpal or metatarsal and the proximal phalanx. The proximal sesamoid bones are located on the caudal surface of this joint.






8. A joint movement that consists of a twisting motion of a part on its own axis.






9. The bones along the central axis of the body; made up of the skull - hyoid bone - the spinal column - the ribs - and the sternum.






10. Skull bones that are part of the internal bones of the face; make up the caudal portion of the hard palate.






11. The microscopic - laminated cylinders of bone that make up compact bone. Oriented lengthwise in a long bone - these consist of a central haversian canal surrounded by concentric layers of bone. Osteocytes in their lacunae are present at the junctions






12. One of the three ossicles in the middle ear; also called the hammer - this bone is the outermost of the three ossicles and is attached to the tympanic membrane.






13. Also known as the spinal column; the collective name for the cervical - thoracic - lumbar - sacral - and coccygeal vertebrae.






14. The bones of the limbs (appendages)






15. The skull bones that do not surround the brain. External bones: the incisive bones - the nasal bones - the lacrimal bones - the maxillary bones - the zygomatic bones - and the mandible. Internal bones: the palatine bones - the pterygoid bones - the v






16. Skull bones; external skull bones of the face. These two small bones form part of the medial portion of the orbit of the eye and house the lacrimal sacs - which are part of the tear drainage system of the eye.






17. A bone of a digit (finger or toe). Pl. - phalanges.






18. The long bone of the brachium or upper arm.






19. The most cranial of the three pairs of bones that make up the pelvis; it forms the sacroiliac joint with the sacrum.






20. The front limb.






21. The first cervical vertebra; it forms the atlantooccipital joint with the occipital bone of the skull and the atlantoaxial joint with the axis.






22. Mature bone cells located in lacunae.






23. The growth plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. They are areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full adult






24. The hind limb.






25. The fibrous membrane that lines the hollow interiors of bones.






26. Tiny channels through the matrix of bone. Threadlike projections from osteocytes communicate with each other and with blood vessels through these structures.






27. Skull bones that are external bones of the cranium; form the dorsolateral walls of the cranium. They are large and well developed in dogs and cats - but small in horses and cattle.






28. The outer layer of a bone that is composed of compact bone.






29. Secondary areas of growth in bones developing by the endochondral method; areas of bone development located outside the main portions of the carilaginous bone templates in a developing fetus.






30. One of the two bones (with the ulna) that form the antebrachium - or forearm; usually the main weightbearing bone.






31. The first - most cranial sternebra.






32. The most common type of bone marrow in adult animals; consists mainly of adipose tissue. Does not produce red blood cells - but it can revert to red bone marrow if the body needs greater than normal blood cell production.






33. The bones of the carpus; consist of two parallel rows of short bones located between the distal ends of the radius and ulna and the proximal ends of the metacarpal bones.






34. The central canal that runs the length of a haversian system; contains blood vessels - lymph vessels - and nerves that supply and nourish the osteocytes.






35. A hole in the bone.






36. The eardrum; a paper - thin connective tissue membrane that stretches across the opening of the external ear canal into the middle ear.






37. A flat articular surface - such as between carpal bones and between the radius and ulna.






38. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






39. The type of bone formation whereby bone grows into and replaces a cartilage model; this is the method by which most bones form in a developing fetus - starting with cartilage 'prototypes' that are gradually replaced by bone. It is also the means by w






40. The bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone; in the living animal - it contains the external ear canal.






41. A skull bone that is one of the external bones of the cranium; the caudal - most bone of the skull that forms the atlanto - occipital joint with the first cervical vertebra through the occipital condyles. The large foramen magnum in the occipital bon






42. A skull bone that is one of the internal bones of the face; forms part of the nasal septum.






43. A band of fibrous connective tissue that is present in and around many synovial joints; connect the bones of the joint to each other.






44. The bones of the skull that surround the brain. External bones: the occipital bone - the interparietal bones - the parietal bones - the temporal bones - and the frontal bones. Internal bones: the sphenoid bone and the ethmoid bone.






45. One of the three ossicles in the middle ear; also called the anvil - this bone is the middle of the three ossicles.






46. An immovable fibrous joint - such as the suture that unites most of the skull bones.






47. The joint movement that increases the angle between the two bones.






48. The end of a long bone; each long bone has a proximal and distal _____.






49. The concave articular surface of the scapula; the socket portion of the ball - and - socket shoulder joint.






50. The process on the distal end of the distal phalanx of dogs and cats that is surrounded by the claw in the living animal.
